Xiaomi (小米) Unveils MiMo-V2-Pro: 1T-Parameter Base Model with 1M Context Window for the Agent Era

Product and technical highlights

Xiaomi (小米) today introduced its flagship base model, MiMo-V2-Pro, designed for high-intensity Agent workloads. The company says the model’s total parameter count exceeds 1 trillion (with 42 billion activation parameters) and it supports a 1 million-token context window. Xiaomi retained the Hybrid Attention architecture from its MiMo-V2-Flash predecessor but increased the hybrid ratio from 5:1 to 7:1 to improve long-context performance.

Benchmarks and comparative positioning

According to the global large-model ranking Artificial Analysis, MiMo-V2-Pro sits eighth worldwide and second in China. Xiaomi says the model performs strongly on Coding Agent, general Agent tasks and tool use, placing it in the same competitive tier as Claude Sonnet 4.6, GPT 5.2 and Google’s Gemini 3.0 Pro. In OpenClaw standard evaluations (PinchBench and ClawEval) the model reportedly ranks among the global leaders. It has also been reported that an anonymous model codenamed “Hunter Alpha” that appeared on API aggregator OpenRouter saw heavy use during its debut, topping daily charts and surpassing one trillion token calls.

Availability and front-end use cases

MiMo-V2-Pro is now available via API and Xiaomi says it will be billed on a tiered usage basis, with support for the full 1M context length. In practical tests cited by Xiaomi, the model demonstrates strong end-to-end web and front-end generation capabilities—producing design-ready, functional pages in one step that balance visual quality with usability.

Why this matters — geopolitical and industry context

China’s leading tech firms are investing heavily to build indigenous large models as the global AI race intensifies and export controls complicate access to some advanced chips and services. Can a domestic stack like MiMo-V2-Pro reduce reliance on Western models? Possibly, but hardware, ecosystem integration and real-world adoption remain the variables to watch. For Western readers, Xiaomi’s move is another sign that China’s AI ecosystem is rapidly maturing and aiming to compete not just on apps but on foundational models.
